When the door is open you see that this is definitely an underground place, lit only by the candle light, no electricity, with jazz music in the background (mostly), and full with people from all around the world. This place offers alternative underground approach to the night life, smoking allowed and cheap drinks included. For example one Shumensko beer will cost you only 3.50 levs.

On the lower level there are bars with stools while up the stairs there are couple of tables with small chairs. It’s a great place for a drink during the winter or later at night in summertime when the outdoor gardens are already closed. Keep in mind that sometimes it might get too smoky because of cigarettes and also if you are planning to drink a little more stay out of the second level, since not only the stairs are tricky to climb, but also there is a lot of ways of falling down.
